Researchers Create an Epic Genetic Atlas of Rice
(PhysOrg.com) -- Yale researchers have published a cellular atlas of genetic activity in rice, documenting with unprecedented detail how and when genes are turned off and on within cells of a living organism.
Study first to pinpoint why analgesic drugs may be less potent in females than in males
(PhysOrg.com) -- Investigators at Georgia State University`s Neuroscience Institute and Center for Behavioral Neuroscience are the first to identify the most likely reason analgesic drug treatment is usually less potent in females than males. This discovery is a major step toward finding more effective treatments for females suffering from persistent pain.
More Men Die from COPD Compared to Women

Intel and Adobe to Extend Flash Platform to TVs
Adobe Systems and Intel today announced plans to collaborate on the development to port and optimize Adobe Flash technology for the Intel Media Processor CE 3100. This effort is expected to provide consumers with richer and more seamless Web-based and video viewing experiences through advanced Intel-based cable set-top boxes, Blu-ray Disc players, digital TVs and retail connected AV devices.
Flawed deposit insurance programs need reform, banking expert says
Government insurance programs that safeguard bank deposits should be reformed to ease taxpayers' undue stake in propping up the nation's banking system, according to research by a University of Illinois finance professor.
New hope for cancer comes straight from the heart
Digitalis-based drugs like digoxin have been used for centuries to treat patients with irregular heart rhythms and heart failure and are still in use today. In the Dec. 16 issue of the Proceedings of the National Academy of Sciences, researchers at the Johns Hopkins University School of Medicine now report that this same class of drugs may hold new promise as a treatment for cancer. This finding...
Cell biologists identify new tumor suppressor for lung cancer
Cancer and cell biology experts at the University of Cincinnati (UC) have identified a new tumor suppressor that may help scientists develop more targeted drug therapies to combat lung cancer.
Prolonged nevirapine in breast-fed babies prevents HIV infection but leads to drug-resistant HIV
Babies born to HIV-positive mothers and given the antiretroviral drug nevirapine through the first six weeks of life to prevent infection via breast-feeding are at high risk for developing drug-resistant HIV if they get infected anyway, a team of researchers report. But the investigators highlight the proven superiority of the six-week regimen in preventing mother-to-child HIV transmission in...
Physicists offer foundation for uprooting a hallowed principle of physics
Physicists at Indiana University have developed a promising new way to identify a possible abnormality in a fundamental building block of Einstein's theory of relativity known as "Lorentz invariance." If confirmed, the abnormality would disprove the basic tenet that the laws of physics remain the same for any two objects traveling at a constant speed or rotated relative to one another.
Folic acid survey of Spanish-speaking women finds most are missing benefits
Only 17 percent of Spanish-speaking women of childbearing age in the United States are taking a multivitamin containing folic acid daily, according to the first- nationally representative folic acid awareness survey to focus on this population.
Effect of subliminal marketing greater than thought
(PhysOrg.com) -- Marketing statements influence us subliminally more than was ever assumed. Even when you are not aware of being exposed to advertising material, it can still affect your actions. This emerged from research by Marieke Fransen of the University of Twente, Netherlands, who obtained her doctorate from the Faculty of Behavioural Sciences on 19 December.
Teaching intangibles with technology
Teach students some facts, and they learn for one exam at a time. Teach students to think and they learn how to learn for the rest of their lives. Ambitious work from European and Israeli researchers is making it easier to help students learn to think for themselves. This is exciting stuff for teachers.
Brown Dwarfs Don't Hang Out With Stars
(PhysOrg.com) -- Brown dwarfs, objects that are less massive than stars but larger than planets, just got more elusive, based on a study of 233 nearby multiple-star systems by NASA's Hubble Space Telescope. Hubble found only two brown dwarfs as companions to normal stars. This means the so-called "brown dwarf desert" (the absence of brown dwarfs around solar-type stars) extends to the smallest...
Iridescence invisible to human eye enables bees to view flowers in different colours
(PhysOrg.com) -- Bees see some flowers in multicolour because of previously unknown iridescence of the petals, usually invisible to the human eye, researchers from the University of Cambridge report this week in Science.
Collagen VI may help protect the brain against Alzheimer's disease
Scientists from the Gladstone Institute of Neurological Disease (GIND), UCSF, and Stanford have discovered that a certain type of collagen, collagen VI, protects brain cells against amyloid-beta (Aβ) proteins, which are widely thought to cause Alzheimer's disease (AD). While the functions of collagens in cartilage and muscle are well established, before this study it was unknown that collagen...
Doubts make consumers more willing to reevaluate brands, study finds
Most consumers crave a clear understanding of brand images, making them more receptive to new marketing messages if anything clouds their vision of companies or products, according to a new study by a University of Illinois marketing expert.

'Recovery coaches' effective in reducing number of babies exposed to drugs
About 11 percent of the 4 million babies born in the U.S. each year have been exposed to alcohol or illicit drugs in the womb, according to a June 2006 report by the National Center on Substance Abuse and Child Welfare. If removed from the home by child protection, these children tend to remain in foster care longer, and chances are very low that they will be reunited with their parents.
